Problems solved by technology

[0003] The existing test device for small-sized samples does not consider the consistency of the sample during the test assembly and the coaxiality of the test piece relative to the loading axis of the testing machine during the test, and the additional bending moment introduced will affect the small-sized sample. The performance test results have a significant impact, resulting in test failure or untrue test data and large dispersion

Abstract

The invention belongs to the technical field of aero-engine part testing, and particularly relates to a small-size I-shaped sample testing device. The device comprises an I-shaped sample, a clamping block, a positioning block, a positioning pin and a switching section. The positioning grooves are formed in the left side and the right side of the first clamping block respectively, a T-shaped through groove is formed in the middle of the first clamping block, the positioning grooves are formed in the left side and the right side of a second clamping block respectively, the T-shaped through groove is formed in the middle of the second clamping block, and the T-shaped through groove of the first clamping block and the T-shaped through groove of the second clamping block form the I-shaped through groove, a first positioning pin is mounted in the positioning grooves in the left sides of the first clamping block and the second clamping block, and a second positioning pin is mounted in the positioning grooves in the right sides of the first clamping block and the second clamping block; an I-shaped sample is arranged in the I-shaped through groove; the positioning block is used for limitingthe I-shaped sample in the I-shaped through groove, and a first switching section and a second switching section are used for connecting the first clamping block and the second clamping block with atesting machine respectively. The device is simple, effective and high in universality.

Description

technical field [0001] The application belongs to the technical field of aero-engine parts testing, and in particular relates to a small-sized H-shaped sample testing device. Background technique [0002] In the research of aero-engine components, the performance data obtained from standard test pieces are often used directly for design and life evaluation. However, the actual parts processing and molding process and working conditions are complex. After molding, the surface finish, crystal orientation, and thin-wall effect of the blade cannot be truly reflected by the standard test piece. If you choose to directly sample the parts on the body, you can obtain true and accurate material performance data. However, due to the size limitation of the parts to be sampled, only non-standard small-sized test pieces can often be taken out. Research at home and abroad has shown that it is feasible to directly cut small-sized samples from parts for mechanical performance testing and ha...
